UNITED STATES PATENT or HUGH WILSON, 0F KNOXVILLE, TENNESSEE.

vAroR MOISTENER.

Application filed June22, 1925. Serial No.38,906.

This invention relates to improvements in internal combustion engines, the general object of the invention being to provide means for introducing vapor or moisture laden air into the explosive charge before it reaches the cylinders, so as to make the same more combustible and thus increase the efiiciency of the engine.

Another object of the invention 1s to provide means whereby the supply of vapor entering the manifold is regulated according to the amount of mixture entering the cylinders.

A further object of the invention is to place the inlet device between the manifold and carbureter and to connect it with the upper part of the radiator so that the air in the upper part of the radiator will be drawn through the device and into the manlfold by the suction created by the moving pistons.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, ref erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a view of a motor of a vehicle showing the invention in use.

Figure 2 is an enlarged plan view showing the device arranged between the carbureter and the intake manifold of a motor.

Figure 3 is a side view of the inlet part of the device.

Figure 4 is a view similar to Figure 3, but showing parts in section.

Figure 5 is a section on line 55 of Figure 4.

Figure 6 is a section on line 66 of Figure 7 Figure 7 is a sectional view through the cam on the operating rod of the spring valve.

Figure 8 is a sectional view through the upper part of the radiator of the vehicle, with the pipe leading to the device arranged therein.

In these views, 1 indicates a member which is formed similar to the gasket located between the manifold and carbureter of an internal combustion engine and this member is substituted for such gasket. It is formed with a horizontal bore 2 in its top part and a plurality of ports 3 extend from this bore through the wall of the large central opening in the member. A nipple 4: is placed in one end of said bore and a pipe 5 is coupled to said nipple and extends through the top part of the radiator of the vehicle and has its hooked end 5' located in the filling spout of the radiator. Thus the moisture laden air or vapor in the top part of the radiator will be drawn through the pipe 5 into the bore through the ports 3 into the large opening in the member 1 which forms a part of the passage leading from the carbureter to the cylinders so that this air will mix with the explosive mixture passing into the manifold from the carbureter.- A spring plunger 6 is arranged in the bore 2 for covering the ports 1 3 and a stem 7 is fastened to the plunger and extends through a slot 8 formed in the top part of the member and which is covered by a slide 9 through which the stem passes. A cam 10 is adjustably connected with the stem by means of the screw 11 and this cam is arranged in the path of the arm 12 of the throttle valve of the carbureter so that when the arm is moved to open the valve, it will strike the cam and thus move the stem and plunger to uncover some of the ports 3, the number of ports uncovered being in accordance with the amount of movement of the arm 12.

From the foregoing, it will be seen that moisture laden air will be drawn from the top of the radiator into the inlet manifold so that it will be mixed with the explosive mixture passing from the carbureter as the engine is operating and the amount of this air entering the device will be in accordance with the quantity of the charge as the plunger 6 which controls the ports 3 is moved by the movement of the throttle valve of the carbureter. The relative proportions of the charge and of the moisture laden air can be regulated by the adjustment of the cam on the stem of the plunger.

It is thought from the foregoing description that the advantages and novel features of my invention will'be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. In an internal combustion engine, a gasket-like member arranged between the inlet manifold and carbureter of said engine and having, a, centrally arrangedopening and a bore infits top and a plurality of ports connecting the bore with the opening, said ports being arranged 111 a row which extends longitudinally of the bore, means' for con necting the bore with the top part of the radiator of the engine, a member sliding in the bore for covering the ports and mean's.

for moving said member;

2. In an internal combustion engine, a' gasket-like membcriplaced between the inlet. manifold and the earbureter of said engine and havinga central opening and a bore in its top and ports connecting the bore with the tle valve of'said engine.

In testimony whereof I affix my signature.

HUGH WILSON.
